Adjacent tissue layers can be accessed using a catheter device with a distal tip having a conductive portion including a first cutting feature and one or more projections extending from the first cutting feature towards an outer diameter of the distal tip. Electrical energy can be supplied to the conductive portion of the device to cut tissue. A stent can be delivered to form a fluid communication between the adjacent tissue layers.

Surgical systems and methods for percutaneously inserting surgical devices, such as during glenoid labrum repairs or rotator cuff repairs of the shoulder, for example, may include a cannula and a cutting obturator insertable through the cannula. The cutting obturator may include a cutting tip configured for penetrating and dilating tissue during a percutaneous insertion into a joint space.

A method of suturing a trocar path incision in a tissue of a patient with an obturator includes inserting the obturator through the tissue such that a shaft of the obturator extends through a tissue opening about the trocar path incision and a distal tip of the obturator is positioned within a cavity of the patient. The method also includes directing the suture via a suturing feature with the obturator inserted through the tissue in order to direct the suture relative to the tissue. Furthermore, the method includes closing the tissue opening about the trocar path incision with the suture.

Provided in the present disclosure is a puncture core assembly, comprising an operating assembly, a puncture core rod, and a puncture tip used for puncturing human tissue so as to form a puncture opening. The operating assembly is manipulated to generate a driving force. The puncture core rod comprises a transmission assembly and an execution assembly. The transmission assembly transmits the driving force. The execution assembly has a suture actuator, and also has a positioning assembly, a suture assembly, a suture thread release assembly, and a suture needle fixing assembly, which are used to perform positioning when suturing the puncture opening, suture out a needle, release a suture thread, and receive and hold the suture needle respectively.

The present disclosure provides a suture line release mechanism, the puncture core assembly, a puncture device, and a use method of the puncture device. The suture line release mechanism includes a release execution component; the release execution component includes a fixing member and a puncturing tip the puncturing tip is provided with a receiving part; the release execution component has an initial state and a release state; in the initial state, a part of the fixing member is received in the receiving part, and a closed suture line receiving space is formed between the puncturing tip and the part of the fixing member; in the release state, the suture line receiving space is exposed.

The present disclosure provides a cannula assembly having a tube with an internal lumen, a proximal end portion and a distal end portion configured for insertion into a patient. The cannula assembly further includes a housing rotatably coupled to the tube between a closed position and one or more open positions. The housing contains an electronic component comprising an image transmission device, such as a camera, for collecting and receiving images of the surgical site. The housing is adapted to provide the image transmission device with a longitudinal or forward view when the housing is in the closed position and a transverse view (i.e., offset from the longitudinal axis) when the housing is in one of the open positions. The housing is disposed distal to the proximal end portion and proximal to the distal end portion of the tube to protect the image transmission device as the distal end portion creates an incision and/or passes through an existing incision in the patient.

A device and method is provided to gain access to interior body regions. The system includes a safety needle, a stylet assembly, a blade assembly, an obturator assembly, a cannula assembly, a handle assembly, an actuator assembly, and a lock assembly. The safety needle accesses an interior body region. The actuator assembly, lock assembly, and handle assembly interact to expose the blade assembly, after which the blade assembly expands the pathway created by the safety needle. The obturator then further expands the pathway and delivers the cannula assembly to the desired location. The safety needle, obturator assembly, blade assembly, handle assembly, actuator assembly, and lock assembly are removed, leaving the cannula assembly in place for future procedures.

A surgical system for preparing the sacroiliac (SI) joint for a fusion, comprising a sliding joint finder and a working cannula. The working cannula comprises a body having a central axis that runs the length of the body. The body of the working cannula comprises a distal end, a proximal end and a central cavity that is positioned along the central axis of the working cannula and has suitable dimensions for sliding the working cannula over the sliding joint finder and the working cannula further comprises two protrusions extending proximally. In addition, the two protrusions have uneven lengths such that when the working cannula is inserted, the longer of the two protrusions engages the SI joint at a superior end of the SI joint and the shorter of the two protrusions engages the SI joint at an inferior end of the SI joint.

An intra-cardiac introducer device includes a sheath having an inner wall and an outer wall spaced apart from the inner wall to define a sheath space, the sheath defining a distal end and a proximal end and arranged to penetrate cardiac tissue. A hub is connected to the proximal end of the sheath, an intracardiac stabilization balloon is coupled to the distal end of the sheath, and an external stabilization disc is slidingly positioned along the sheath. The cardiac tissue is sandwiched between the intracardiac stabilization balloon and the external stabilization disc to secure the position of the sheath in the cardiac tissue.

Example embodiments relate to devices, systems, and methods for performing a surgical action. The device may comprise a port assembly, a camera arm assembly, and an instrument arm assembly. The port assembly comprises an access port and a plurality of anchoring portions. The camera arm assembly comprises at least one camera at a distal end and is configurable to insert into the access port and attach to one of the anchoring portions. The instrument arm assembly comprises a serial arrangement including a plurality of arm segments, a plurality of joint portions, and at least one end instrument attached to one of the arm segments by an instrument joint portion at a distal end. Each joint portion is configurable to provide an attached arm segment with at least one degree of freedom. Furthermore, the instrument joint portion is configurable to provide the end instrument with at least one degree of freedom.
